Commissioning filled and charged batteries For commissioning of unfilled batteries see separate instructions! The battery should be inspected to ensure it is in perfect physical condition. The charger cables must be connected to ensure a good contact, taking care that the polarity is correct. Otherwise battery, vehicle or charger could be damaged. For the assembly of harness cables or in case of the replacement of a connector the following torque must be applied: M 10 perfect connector 25 ± 2 Nm In case the interval between delivery (see manufacturing date on type plate) and commissioning is longer than 8 weeks or the electrolyte level sensor is indicating low electrolyte level (see table point 3.1.1), the electrolyte level has to be checked. If the battery is equipped with a single point water topping up system (optional), for the removal of the BFS plugs only the appropriate tool must be used. Otherwise the floats of plugs may be permanently damaged, which can cause overflow of the cells. If the electrolyte level is below the top of the separator, it must first be topped up to this height with purified water (IEC 62877-1 : 2016). Then the battery can be charged as in item 2.2. The electrolyte should be topped up to the specified level with purified water. Fiamm Motive Power Water Less®/ Water Less® 20 batteries are fitted with an electrolyte level indicator. 2. Operation EN 62485-3 “Traction batteries for industrial trucks” is the standard which applies to the operation traction batteries in industrial trucks. 2.1 Discharging Be sure that all ventilation holes are not sealed or covered. Electrical connections (e.g. plugs) must only be made or broken in the open circuit condition. To achieve the optimum life for the battery, operating discharges of more than 80% of the rated capacity should be avoided (deep discharge). This corresponds to an electrolyte specific gravity of 1.14 kg/l at 30°C at the end of the discharge. Discharged batteries must be recharged immediately and must not be left discharged. This also applies to partially discharged batteries. 2.2 Charging Only direct current must be used for charging. All charging procedures in accordance with EN 41773-1 and EN 41774 are permitted. Only connect the battery assigned to a charger, suitable for the size of battery, in order to avoid overloading of the electric cables and contacts, unacceptable gassing and the escape of electrolyte from the cells. In the gassing stage the current limits given in EN 62485-3 must not be exceeded. If the charger was not purchased together with the battery it is best to have its suitability checked by the manufacturers service department. When charging, proper provision must be made for venting of the charging gases. Doors, battery container lids and covers of battery compartments must be opened or removed. During the charge the battery must be removed from the closed battery compartment on the truck. The ventilation must comply to EN 62485-3 standard. The vent plugs should stay on the cells and remain closed. With the charger switched off connect up the battery, ensuring that the polarity is correct. (positive to positive, negative to negative). Now switch on the charger. When charging the temperature of the electrolyte rises by about 10°C, so charging should only begin if the electrolyte temperature is below 45°C. • Pay attention to the operation instruction and fix them close to the battery. • Work on batteries to be carried out by skilled personnel only! • Use protective glasses and clothes when working on batteries. Pay attention to the accident prevention rules as well as EN 62485-3 and EN 50110-1. • No smoking! • Do not expose batteries to naked flames, glowing embers or sparks, as it may cause the battery to explode. • Acid splashes in the eyes or on the skin must be washed with water. In case of accident consult a doctor immediately! • Clothing contaminated by acid should be washed in water. • Risk of explosion and fire, avoid short circuits! • Caution: Metal parts of the battery are always live. Do not place tools or other metal objects on the battery! • Electrolyte is highly corrosive. • Batteries and cells are heavy. • Ensure secure installation! Use only suitable handling equipment e.g. lifting gear in accordance with VDI 3616. • Dangerous electrical voltage! • Pay attention to the hazards that can be caused by batteries. Traction batteries with positive tubular plates type PzM / PzMB Ignoring the operation instructions, repair with non-original parts or using additives for the electrolyte will render the warranty void.
